1585 | * | |
1586 | * This table is generated using the helper macros defined above and with | |

1588 | * into .name and for STR and INT types, the offset of the target buffer within | |
1589 | * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar | |
1590 | * offset to the field containing the length of the configuration variable. | |
1591 | * .param3 and .param4 can be used to mark the allowed range (length for STR | |
1592 | * and value for INT). | |
1593 | * | |
1594 | * For each configuration line in wpa_supplicant.conf, the parser goes through | |
1595 | * this table and select the entry that matches with the field name. The parser | |
1596 | * function (.parser) is then called to parse the actual value of the field. | |
1597 | * | |

1599 | * since only one line needs to be added into this table and into the | |
1600 | * struct wpa_ssid definition if the new variable is either a string or | |
